Nine inch drum/drum should not have a P valve.
It should have just a distribution block with the safety switch in it. Because of it's location it will be spotless inside.The only moving part inside it is a shorting plunger to turn on the dash lite if you have a pressure differential across the two systems;front and rear.
Are they available for purchase. And from Who? What's it called? Thanks. My guy has the car on the lift and I want to keep him happy with parts flowing in next week.
